Smelt something burning when using microwave, why??

[shoooer]

:confused: My microwave maybe has any faults!! I always smelt something burning when using it, only first seconds. I examined and scrubbed it, but nothing leftover inside of this discount shopping microwave. Have you come across this problem? Do you know why? The brand of my microwave is Bosch, and the model number is HBC84K521B, Bosch HBC84K521B Compact Built-in Oven and Microwave. Do you know why? Please let me know! Thank you!

What does it smell like? Electrical has a distinct smell. We had a coffee maker that had a weird plastic smell to it when it was new. I attributed it to cheap parts and we bought a new one. The coffee maker was a no brand and free with some brand of coffee my wife bought. Just reinforced my belief that you get what you pay for. :pat:

What are you microwaving on? Could it be plastic you smell?
